JAMES CHARLES POTTER, OF PAWTU'GKET, RHODE ISLAND,

SPINNING AND TWIS'IING MACHINE.

Application filed December 24, 1921.

To all w ham 2'25 may concern Be it known that I, JAMES C. POTTER, residing at Pawtucket, county of Providence, and State of Rhode Island, a citizen of the United States, have invented certain new and useful Improvements in Spinning and Twisting Machines, of whichthe following is a specification.

The spindles of spinning machines, by the usual practice, are driven by bands in the form of round belts which run from the tin roller to the spindles, there being such a band for each spindle, and by tapes which are fiat belts that likewise'run from the tin rollers to the spindles, a tape, however, driving 4 spindles and a tension roller being employed for each tape to take up slack therein. The first mentioned or band driving is objectionable because it is subject to variations in tension so that, for example, in damp weather the band stretches and becomes so loose that it slows down the speed of the spindle and is apt to jump the whirl which is objectionable first, because it stops the running of the spindle and time must be taken to replace it, and it climbs or works up the bobbin to the ruin of the yarn wound thereon. When thoroughly dry the band may become so tight as to break. Again, when it is desired to reverse the twist of the yarn say from right to left, every band must'be changed so as to reverse the direction of revolution of the spindles. The tape drive from the tin roller is faulty because as a result of the quarter turn of the tape on the run from the horizontal tin cylinder to the vertical spindle on one side of the tin roller, and on the run from the'tension roller to the spindle on the other side of the tin roller and the necessity of placing the, tension roller to one side of the direct line of draft from the tin roller to spindle, the tape does not bear flat and smooth against the periphery of the tin roller but is slightly askew so that one edge of the tape may have no contact withthe tin roller and the work i falls upon the other edge and the tape shifts laterally backand forth upon the tin roller, the result being that the drive of the spindles is not steady and the tape rapidly wears out and adds to the dirt produced to'the possible injury of the yarn. Should change of twist of yarn, as from right to left, be necessary, it would not be practicabletoaccom plish that by rearangement of the tape corresponding'with the crossing or uncrossing Serial No. 524,681.

of the band in the band type of drive. An important object of my invention is to provide a spindle drive which will overcome the defects of the band and tape drives above mentioned, Another important object of my lnventlon is to enable the use of the tape drive as the tape is preferable to the band even when, above described, the tape is open to the obections I have noted. Still another important object of my invention is the provision of an lmproved spindle drive in ringsplnnmg or twisting machines of the type in whlch the ring-rails are stationary and the splndles are traversed by the builder motion, such a type being patent of December 27, 1921. My inventlon consists in any machine having the characteristics of construction defined by or included withinthe .scope of the appended claims.

In the accompanying drawings which form a part of this specification, I illustrate my invention as embodied in a machine of the type of my before mentioned patent, that is to say, a ringspinning machine in which the spinning railis stationary and the spindles traverse through the rings. In such drawings: I

Fig. 1 is a top plan view of a portion of a spinning machine embodying my inven tion;

Fig. 2 is a vertical of Fig. '1;

of Fig. 1.

Proceeding now with a description in detail of what is shown in thedrawings, 10 designates, the stationary ring-rail, there being, as usual, one at both front and back of the machine, 11., therings thereon,-and

12, the travelers to which the yarn runs from ment of the carriage to effect the traverse the rings in build{ of the spindles through ing the cop is accomplished.

Midway between the spindles from front to back of the machine I mount a series of vertical drums or wide faced pulleys, 15,

as in the ordinary practice,-

the subject of my section on the line 2-2 0 Fig. 3 is a vertical section on the line 83.

there being one, preferably, for. two, opposite boxes of spindles, and from each druni an endless tape, 16, is run to the boxes or groups of spindles associated. tl1Gl7B\V1i3h,-

the run of thettape' fronrth'e drum to the first spindle of, a bore I place atension' pul ley, 19-, which is slidably supported by: a cross-bar, 20,- that extendstroni' one carriage raila to, the other so that the tensionroller while movable horizontallyto'lake' upslack' in the, tape"- and maintain the desired tension of the-tape participates inthe'vertical move ment of the, spindles with: the carriage and 1 in. consequencerof such vertical i movement of the; spindles with; their whirls, the idlers and the tension roller, the tape 111OV6S-VBP4 ticallyi sliding'up andidown over ther perip'h cry of the :widefaoedpnlley andithus=at all tiineslin the vertical-movement otithe' spin dlesthe driving connection with thedruni is maintained although the drum itself is stew tionarily supported The tension' roller-is mounted, on a vertical shaft, 21', that has hearings in a bracket, 22, thatdias' a slidableconnection with thecrossbar; 2.0-,- Iand' said bracket has an eye or.v ring; ;23, ,WliiClli'iSi en-r gaged by a hook, 24, on one end of a rope:-

Each dlllll] or wide faced pulley, 15, is fixed-to, the upper endtota vertical shaft, 80, mounted in bearings supported by a horizontal rail-,- 31,,and below such rail has a spiral gear, 32, on a long horizontal driving: shaft, 33-, isaspiral gear, 34, for each drum shaft, 30, which meshes with the spiral gear, 32, on suchsha-ft, and amen] otthev drums. are driven by'the shaft; At-one end the" driveshaft, 33,- lias a pulley; 35, which receives motion from a suitable source iLIlCliWhlGlTzPllllBYiS rotated in one=direction or the other according to: whether the twist 59 ofth'eiyarnvisi'tobe rightorleft.
